SUMMARY OF S.R.M

what is S.R.M.?The Stretch Reducing Mill (S.R.M.) consists of24 roll stands, each containing 3 rolls, adesign that improves internal surface finish, maintains concentricity, and improvesdimensional accuracy. Each roll stand reduces pipe diameter by approximately 5%, withthe final 3 stands providing the finish diameter. Also, by controlling longitudinal tensionbetween each stand at the same time, it can also reduce, maintain, or increase wallthickness, resulting in a wide variety of diameters & wall combinations to meet thecustomer specifications.

The S.R.M. at our Pohang plant consists of8”E.R.W.pipe mill, induction furnace,thickness control system, main unit, flying hot saw, cooling bed, etc. All lines aredependant on the centralized automatic control system, which is only one of its kinds inSouth Korea.

To begin the stretch reducing process, pipe hollows are heated to an austenite conditionof approximately 950 ~ 1050 degrees Celsius by 10 induction furnaces before enteringthe Stretch Reducing Mill. This process inhibits the oxidation scale along with the graingrowth. Also, the pipe for the S.R.M. will have received a uniformed heat.

1. LARGE QUANTITY PRODUCTION

2. UNIFORMED HEAT TREAT RESULTS IN TOP QUALITY MACHINING &

COOLING

3. COMPLETE REMOVAL OF ALL INNER PIPE BEAD FOR ALL SIZES

4. PRODUCTION OF SCH. 80 & HEAVIER AS WELL AS SPECIALTY PIPES

5. PRODUCTION OF VARIOUS DIAMETER & SMALL LOT
